Okay, we can't have any actual person on person violence, so just have her steal Robinson Crusoe's whistle.

That'll teach him.

Nearly done guys. She got the whistle, escaped the animals, and Robinson Crusoe is left gaping in his stupid hat.

So that's our exciting story? An old man on an island with pets and a whistle? That's actually not very exciting.

Well, he was, um, let's say, planning on, um, attacking the world with his whistle-controlled animals. But Supergirl stole the whistle and without the whistle he couldn't control the animals so they killed him. Case closed!

So it's like Supergirl basically killed the old guy?! That's terrible! We can't print that. Girls all over Britain will be reading this book on Christmas morning, going out in the afternoon, and killing every whistle-bearing grandpa they see!

Yeah, this is completely unacceptable. A bionic girl with a TV-equipped crutch who leaps over ravines, punches sharks, and kills Robinson Crusoe? I don't think so. Our readers deserve better.
